HOW IT WORKS
NOTICE
• Failure to remove or replace by the “remove
or replace before” date, as shown on the
product label, could diminish the effective-
ness of the product.
• Primary activation method is through
electronic sensors.
• At time of activation (deployment), a loud
“POP” will occur, followed by 3 long,
repeating tones. This is normal and meant
to alert occupants, if present.
• Device is equipped with a fuse that works
as a secondary activation method in case
of dead batteries.
• Replace batteries as required to ensure
optimum performance. Do not mix old and
new batteries. It is recommended that you
not mix brands.
• When testing the unit, do not expose
bottom of the canister toward bright lights
while testing the device.
• A self-test should be manually performed
once every month for the life of the product.
• Unattended cooking is the leading cause of
fires in the kitchen. Many injuries occur when
occupants attempt to fight the fire themselves.
• Never leave anything cooking on the stove top
unattended! If you have to leave the kitchen
—even for a short time— turn off the stove.
• Never leave home or fall asleep while you are
cooking.
• Never pick up a flaming pan. You may be
burned, or if the pan is dropped, flames may
quickly spread to other flammable areas.
• Never use water to fight a grease fire! A violent
explosion may result. Wet dishcloths or towels
are also dangerous.
• Always follow National Fire Protection
Association (NFPA) guidelines for proper
cooking safety. Visit www.nfpa.org.
